Peers have described him as “one of the leaders of the next generation,” praised for his “impeccable knowledge of arbitration,” “deep understanding of arbitral procedures,” and his “bold and creative writing style.”

An alumnus of the University of Malaya (LL.B.) and Columbia University School of Law (LL.M.), where he was a Fulbright and Harlan Fiske Stone scholar, Mr. Leong is admitted to the Malaysian Bar and is fluent in Bahasa Melayu and conversant in Mandarin Chinese.

The SIAC Secretariat currently comprises 17 lawyers qualified in 13 jurisdictions.
